This invention relates to improvements in sterraised portion 1 concave on its underside to perilizing and warming devices for containers, and. mit water to circulate freely beneath it, and the is primarily intended for sterilizing and warming central portion 3 of the base is spaced only infants feeding bottles and nipples, and keeping slightly above the bottom of the pan.

Due to the narrow spacing between Figure 4 is an enlarged sectional view showing the central portion 8 of the base 6 and the bottom a nipple mountedfor sterilizing upon one of the of the pan I water therein boils furiously and 45 tubes. is expelled through-the tubes I5 when the upper Referring to the drawing, I designates a pan surface of the water is barely agitated.

The latter consists of a base 5 amount of steam, sufiicient however to sterilize the periphery of which rests upon the bottom of the outsides of the bottles, is. generated, and withthe pan. The base is provided with an annular out necessitating boiling the water so fast that 55 an appreciable amount of steam pressure is built up within the vessel. The lid 3 is suitably apertured at 3a to permit the escape of steam if for any cause the device is left too long over too fierce a fire. The lid 3 is also provided with a handle 3b.

In Figure 1 it will be noted that two bottles A and AA of difierent lengths and contours are arranged over the tubes [5. The shorter bottle A is prevented from resting upon the upper extremity of its tube by one of the springs 16. In that manner a free flow of water from. the tube into the bottle for washing and sterilizing it is assured irrespective of the height of the bottle. Again the springs l6 are so formed that they will support the smaller outer portion BB of a nipple B, thereby insuring a free circulation of water into the nipple and particularly through its portion BB through which the infants food passes.

When the device is used for warming filled bottles, the tubes l5 are removed from their ferrules 9 and the pan is filled with hot water to any desired depth.

While in the foregoing the preferred embodiment of the invention has been described and shown, it is understood that the construction is susceptible to such alterations and modifications as fall within the scope of the appended claims.

What I claim as my invention and desire to secure by Letters Patent is:

1. A combination bottle sterilizer and warmer comprising a container, a base removably supported on the container and having its margin resting upon the container bottom, the remainder of the base being spaced above said bottom and being apertured for the passage of fluid into the space between the base and the container bottom, an open tray designed to support a bottle in upright or inverted position supported by and over the base at a point substantially below the top of said container, a guide supported by said base above said tray for guiding the bottle to the tray 7 and holding it in vertical position, a ferrule extending. upwardly from the base providing fluid passage from the under side thereof, said ferrule being in vertical alignment with an open portion of said tray, and a tube removably associated With said ferrule extending through the open portion of said tray.

2. A combination bottle sterilizer and Warmer comprising a container, a base removably supported on the container and having its margin resting upon the container bottom, the remainder of the base being spaced above said bottom and being apertured for the passage of fluid into the space between the base and the container bottom, an open tray designed to support a bottle in upright or inverted position supported by and over the base at a point substantially below the top of said container, a'guide supported by said base above said tray for guiding the bottle to the tray and holding it in vertical position, a ferrule extending upwardly from the base providing fluid passage from the under side thereof, said ferrule being in vertical alignment with an open portion of said tray, a tube removably associated with said ferrule extending through the open portion of said tray, and a removable cover for said container apertured to permit the passage of steam therethrough.
